Q&A - NewRelic NaN value not supported

[nadavhames]

Question

Hi, I am piping host_metrics source into newrelic sink, and I am receiving the below errors repeatedly. My guess is that a metric inside of host_metrics returns NaN and newrelic sink does not support NaNs for some reason.
This is ok by me - is there any way to silence these errors if they are expected? Thanks.

Hi @nadavhames, these errors indicate a real issue so we want to keep them generally. However, you can introduce a remap transform and filter out events with invalid metric values.
